We often develop R code for performing landscape genetic and related analyses. Any of our published code can be found here.

Multiple Matrix Regression with Randomization (R function: MMRR)
MMRR presents a method for quantifying and disentangling the relative effects of isolation by distance (IBD) and isolation by environment (IBE). In practice, this method can easily be extended to quantify the relationships between any number of explanatory variables that can be represented as distance matrices and a given response variable (e.g. genetic distances).
